After the introduction of Gammarus tigrinus in The Netherlands some 25 years ago and of other recently invading amphipods (Crangonyx pseudogracilis and Corophium curvispinum) the native species decreased, the invaders increased. The success of these invaders and its impact on the local amphipod fauna is discussed. Electrophoretic tests give evidence that a second invasion of Gammarus tigrinus, this time from Germany, is taking place. Some predictions about future developments are made.

Corophium Curvispinum

Densities of Corophium curvispinum Sars, 1895 collected from stones at two localities (Lobith and Nijmegen) in the Lower Rhine at a water depth of 2-3 metres during 1992 were found to be very high. At both localities Corophium was the dominant macroinvertebrate, outnumbering all other species by many times. The population of the zebra mussel (Dreissena polymorpha) was further reduced in 1992, because all stones are covered with a 1-4 cm thick layer of muddy tubes of Corophium. Muddy material including macroinvertebrates fixed by Corophium was found to be 61-609 g DW m-2 and 9-99 g AFDW m-2 stone surface.

Lower Rhine

In densely populated European countries like the Netherlands, old landscape elements such as ancient woodlands and ancient hedges are today rare. Owing to the introduction of exotic species and indigenous trees and shrubs imported from other climate zones, recognition of truly wild, i.e. autochthonous, individuals and populations is now problematical, posing challenges for forest management agencies, particularly at Natura 2000 sites. The author has developed a method for recognising genetically pure wild woody species, based on characteristics of the plant itself and those of the growing site. With this method, explained here, around 70% of the Netherlands has been surveyed, along with much of Flanders and part of the lower Rhine region of Germany. The results are illustrated with reference to two Dutch ancient woodlands, where new insights were obtained in terms of native status of the woody species and the ‘authenticity’ of the tree and shrub layer.
